If the extension of the spring with the unknown blue mass is 12 cm, determine the value of the load (in kg). Use the spring constant determined in the previous answer. Use the gravitational constant as 10 m/s_squared. Give only the number as an
answer, do not include the unit when entering the number in the block below

Which example has gravitational potential energy? a.a horse slowing down from a run b.an apple about to fall from a tree branch c.a bicycle being pedaled down a horizontal path d.beaker sitting on the floor

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?
